I don't think it is an either or thing. Egor is amazing with the ball in his hands, so I assume he will be initiating the offense most of the time, Hall will facilitate when Egor is on the bench and at times when both are on the floor.

It takes a lot of energy to facilitate the offense, so they will share that burden. Both can play off the ball some. It shows them to contribute in other ways and to keep the other team off balance.
